  • Patent number: 11845294
    Abstract: Disclosed is a keyboard for an information handling system. The keyboard includes a top cover comprising a polyester and a plurality of jute fibers, a keycap assembly comprising one or more keycaps, and a bottom cover comprising a first polylactic acid (PLA) and a post-consumer resin (PCR). The keycap assembly can be positioned between the top cover and the bottom cover, and the top cover can include one or more openings keycap assembly keycaps to protrude through.

  • Publication number: 20230114345
    Abstract: A method for selecting sustainable materials for components of the information handling system can improve sustainability in a cost-effective manner. The method may analyze and determine component configurations with a goal of increasing (e.g., maximizing) overall sustainable material weight contribution by the respective product category and decreasing (e.g., minimizing) cost impact to overall company revenue and/or margin. In determining component configurations, the method may consider parameters including baseline weight, bill of materials (BOM) of the product, sustainable materials attainable, sustainable materials weightage, and/or program decision.

  • Patent number: 11450159
    Abstract: Controlling states of a shutter, including receiving a signal indicating to adjust a shutter of a camera from an open state to a closed state; in response to the signal, mechanically adjusting the shutter of the camera module from the open state to the closed state; after adjusting the state of the shutter of the camera module from the open state to the closed state, receiving a signal indicating that a state of a pin indicates that a lock latch is engaged with the shutter to mechanically interfere with movement of the shutter from the closed state to the open state; detecting an attempt to adjust the state of the shutter of the camera module to the open state from the closed state, and in response, preventing mechanical adjustment of the state of the shutter of the camera module to the open state from the closed state.

  • Patent number: 11240925
    Abstract: A cable management system for a cable in a dock capable of physical connection with an information handling system. The cable management system is configured such that rotation of a bottom cover in a first direction engages a gear and rotates a plurality of gears to extend the cable from the dock and rotation of the bottom cover in an opposite direction disengages one or more of the gears, wherein rotation of the bottom cover retracts the cable and friction forces apply tension to the cable to prevent the cable from tangling during retraction. A plug protection system covers the plug when the cable is retracted to protect the plug and uncovers the plug to allow extension of the cable for physically connection of the plug into a port in an information handling system.

  • Patent number: 8414112
    Abstract: A printing material delivery system includes a printing material storage that includes a printing material. The printing material deliver system also includes a print head. A pressurizing device defines a housing that includes an inlet coupled to the printing material storage, an outlet coupled to the print head, and that houses a rotatable member that is operable to rotate and create a pressure differential in order to transfer the printing material from the printing material storage, through the pressurizing device, and out of the print head.

  • Patent number: 8112012
    Abstract: A printer ROS window cleaning system enforces unidirectional cleaning motion through a passageway formed in the printer housing. A guide has a distal portion that engages a cleaning tool from insertion until a cleaning portion reaches the rear of the passageway. A cleaning tool deflector positioned at the rear of the passageway biases the cleaning tool from the distal portion of the passageway to a proximate portion so that the cleaning portion contacts the ROS window. A unidirectional cleaning feature ensures that the cleaning portion will contact the ROS window during removal of the cleaning tool by preventing re-insertion of the cleaning tool in the proximate portion of the passageway.
